What is HTTP?

HTTP Stands for HyperText Transfer Protocol. It is a protocol used to request, view and transfer files across the internet. HTTP is the most important protocol on the World Wide Web and it is how web pages are accessed. This is why URLs begin with http:// - to let the browser know you are making an HTTP request.

HTTP requires a client program at one end (e.g. a browser such as Internet Explorer or Mozilla) and an HTTP server at the other end. For more information about this system, see How the Internet Works.
